I have an '87 36' flybridge sedan. The roller on the sliding door is shot. The mechanism is corroded and the assembly needs to be replaced. No visible identification on the part. Teflon track won't help, as the roller is disengaged and the foot of the door is bottomed out on the track. Any help in identifying this part and a source for a replacement?

I've found a replacement at our local big box home hardware in the sliding door/screen door section. Pull it out and bring it with you - I can't remember if I bought the cassette or just the wheel with pins. You'd think I'd know - i've fixed two doors now

Same situation, eventually, on our sliding screen door. I was able to dismount the screen, move top trucks to bottom and vice versa, remount the screen, all good.
